$menuBarExists = isset($this->menuBar);
Do not call this method. This is a PHP magic method that we override
to allow using isset() to detect if a component property is set or not.
Note, the control must be configured in the template
with explicit ID. If the name matches both a property and a control ID,
the control ID will take the precedence. public function __isset($name)
{
if (isset($this->_rf[self::RF_NAMED_OBJECTS][$name])) {
return true;
} else {
return parent::__isset($name);
}
}
